Patent GB-1305109-A (GB)
IPC: B61K9/06
Filed: 1970-03-24
Abstract: 1305109 Recording hot axle boxes GENERAL ELECTRIC CO 24 March 1970 [3 April 1969] 14210/70 Heading B7N In a hot box detector system having a remote recording arrangement the detector is connected to the remote location by a pair of channels which transmit the heat signals, a " recorder on " signal and alarm signals indicating an overheated journal. Sensors A and B on each side of the track and wheel detector 8 apply their output signals to detector 10. The detector supplies read signals on line 31 to a timer 44 which controls the opening of gates 45, 46, and these supply a constant amplitude output signal for a duration controlled by amplitude to width converter units 41, 42 fed with the sensor output signals. The width modulated A pulses pass directly to transmitter 16 and the width modulated B pulses pass to the transmitter via opened gate 49. Gate 49 is switched to pass the B pulses by recorder control signal on line 1 which is generated when a train is present. In the absence of a train the gate is controlled to provide a constant " 1 " output which with the constant " 0 " on output A signals " recorder off ". The heat signals are also applied to alarm panel 12 which provides an alarm when an overheated journal is detected. This signal controls gate 47 which supplies a pulse via delay circuit 48 to prevent opening of gate 49 for the first 2 m. secs. of each B pulse. The transmitted signals are demodulated at the remote recording location by receiver 20. When the fixed " 0 " on line A and " 1 " on line B change to " 0 " on both lines the change is detected by unit 64 and the recorder is switched on. The signals on lines A and B are also applied to width to amplitude converters 51, 52 which are sampled by timing pulses developed in unit 54 from the width modulated pulse chains. The sampled signals are held in memories 57, 48 and transferred via gates 61, 62 as fixed duration amplitude modulated pulses to recorder 24. Unit 63 serves to detect the B pulses with 2 m. sec. delay and provides an output to converter 52 to add the missing portion to the pulses and also to provide an alarm signal to the recorder.

Title: Improvements in or relating to process for purification of tyrosine
IPC: C23C22/34
Filed: 1953-05-21
Abstract: Tyrosine is recovered from protein hydrolysates by admixing a tyrosine-leucine mixture with sufficient water or mother liquor from a prior tyrosine crystallization step at a temperature between about 60 DEG  C. and about 100 DEG  C. to substantially completely dissolve the tyrosine from the said mixture, separating the solid material from the hot solution, cooling the resulting solution and separating crystalline tyrosine therefrom.  Prior to separating the solid material from the hot solution, activated charcoal may be added, e.g. in an amount between about 5 per cent and 15 per cent by weight.  The crude tyrosine thus obtained may be further purified by a repetition of the process.  Preferably the tyrosine is dissolved at 80 DEG  to 95 DEG  C.  The liquor from the last crystallization step may be used to dissolve the initial tyrosine-leucine mixture.
